In an attempt to provide a rational basis for the optimization of citric acid production by A. niger, we developed a mathematical model of the metabolism of this filamentous fungus when in conditions of citric acid accumulation. The present model is based in a previous one, but extended with the inc
Models for the known glucose transporters in Aspergillus niger and for simple diffusion of glucose through the hyphal membrane were prepared. The results from the models were compared with fermentation data from published studies on citric acid. It was found that the purely physical and uncontrolled
## Abstract The oneβ and twoβbond ^13^C isotope shifts, typically β1.5 to β2.5 ppb and β0.7 ppb respectively, in nonβcyclic aliphatic systems and up to β4.4 ppb and β1.0 ppb in glucose cause effects that need to be taken into account in the adaptive NMR spectral libraryβbased quantification of the
